Application filed October 7, 1910. Serial No. 585,753.

To all whom t may concern Be it known that I, CHARLES E. BoNINF., ofPhiladelphia, in the county of Philadelphia and State of Pennsylvania,have invented certain new and useful Improvements in Incubators, whereofthe following is a specification, reference being had to theaccompanying drawings.

My invention relates to incubators for tile artiticial hatching of eggs,in which ,meal s for maintaining a carefully regulated temperature areprovided for a series of incubator compartments, each compartment ha.v.ing suitable trays for the support of eggs at varying distances from theheating means.

The invention relates more particularly to the arrangement andconstruction of t-he compartments with relation to a unitary heatingsystem applied to the entire series of compartments, and also to themeans for moving and adjusting the trays in each compartment.

An incubator embodying my invention is shown in the accompanyingdrawings, in which-Figure I, is a side elevation of the incubator. Fig.II, is a longitudinal section of the same. Fig. III, is a cross sectionof the same alon the line III, III, of Il'ig. I. Fig. IV, is a etailedsectional view of a part of the bottom of one ot'the incubatorcompartments showing the means for regulating the height of the eggtray.

The incubator compartments 1, of the incubator. are arranged in parallelrows mounted a suihcient distance from the floor of the incubator houseon legs 2, 2. In this way each compartment may be provided with a hingeddoor 3, and at the same time the whole series are conveniently heated bya single heating system.

At one end of the incubator is a *special` compartment 5, containing twointerlock-- ing manifolds 6, 6, communicating at their ends respectivelyonefwith a pipe 7, for the feeding of hot water, and the other with apipe 8, for the return of cold water to the heating apparatus 9. Thisheating apparatus will not be here described since .it

across the entire top of the incubator and a number of them traverseeach compartment until they reach the other end of the incubator, wherethere is provided a special compartment 12, containing the header 13,with which all of the. pipes communicate. In this way hot water from themanifold 6, is led by every other pipe of the series to the header 13,and returned by the alternate pipes, so that the distribution of theheat in the horizontal series is evenly leii'ected across the entirespace of each incubator compartment as traversed by they pipes. Theheating pipes are supported near the top ofeach compartment, which inconjunction with suit-ably arranged openings in the walls of thecompartments, cause the warm air to be circulated over and around theeggs.

Within each compartment there is supported an egg tray 15, consistin ofa suitable frame with an open or latticed bottomv coveredy with wiremesh, above which the edges rise sufficiently to hold a layerof eggsresting on the bot-tom. 'To the bottom of the tray is secured asupporting frame 16, mounted on a vertical arm 17, slidably mounted in asupporting bracket 18. A rack 19, formed upon one edge of this arm is inengagement with va pinion 20, fixed on a shaft 21, which carries at Aitsforward eX- tremity a crown wheel 22, with teeth in engagement with thecrown 23, conveniently formed upon the casting which forms the bearingfor the shaft 21. rIhe crown wheel and crown are normally kept inengagement by means of Ithe compression ot a spring 25, interposedbetween the pinion 20, and the adjacent bearing of the shaft, but bymanipulating the crown wheel 22, the shaft may be drawn against thepressure of this spring so as to disengage 'the crown wheel from itscrown, permitting the turning of the shaft, so that the pinion byengagement with the rack on the arm 17, may raise or lower each egg traythe desired distance. When this has been done, the reengagement of thecrown wheel `with, its crown immediately takes place, so that the trayis supporte at the desired height. rIhis arrangement is a veryconvenient one because it is necessary to alter from day to day thedistance between the heating pipes and the egg trays. By the Ameanswhich I without otherwise opening the incubator compartment; and as theaperture through Which the arm 17', passes down through the bottom ofthe compartment is a tight one, there is no loss of atmosphere Withinthe incubator compartment attendant upon the adjustment of the tray.

Having thus described my invent-ion, l claim l. In an incubator, an'incubating coinpartment, an egg tray, and means for supporting the sameincluding a vertical arm passing through the bottom of the compartment,and means for moving and setting the arm at any desired position,Without opening the compartment, said means including a rack on the arm,a longitudinally movable shaft carrying a pinion engaging therack, and aspring acting on the shatt for moving it longitudinally to hold it inlocked position against a stationary part of the apparatus.

noaaoia 2. ln an incubator comprising incubating compartments withheating pipes at the top thereof, and an egg tray Within eachcompartment supported upon a single vertical arm projecting through thebottom of the compartment, means for moving and setting the arm at anydesired distance from the heating pipes in the compartment, Withoutopening the same, said means including a rack on the vertical arm, ashaft carrying a pinion en aging said rack, a crown Wheel on said sha t,a crown normally engaged byl the crown Wheel, and a spring'controllingthe shaft to cause such engagement.

ln testimony whereof, l have hereunto signed my name, at Philadelphia,Pennsylvania, this sixth day of Catcher, 1910.
